· YbAs

YbAs is a rare-earth arsenide semiconductor compound in which ytterbium is bonded to arsenic, forming a III-V intermetallic semiconductor material. This compound is primarily of scientific and research interest for its unique electronic properties related to rare-earth doping and strong electron-phonon coupling effects. Applications are largely exploratory, focusing on low-temperature physics, magnetism studies, and potential optoelectronic or thermoelectric device research rather than conventional industrial manufacturing.
